Resizing of Boot Volume

Summary:

I am trying to resize a boot partition I have on an Oracle Linux instance. I already adjusted it online via the GUI but the issue I have is with the commands that follow.

sudo dd iflag=direct if=/dev/<device_name> of=/dev/null count=1

echo "1" | sudo tee /sys/class/block/<device_name>/device/rescan

The first command seems to work fine but the:

echo "1" | sudo tee /sys/class/block/<device_name>/device/rescan says "no file or directory".

My df -h looks like this:


and I was using /dev/mapper/ocivolume-root as the device_name in the commands above.

Howdy, Stranger!
